The two side membersi8 Reierringto the drawing, the numeral l0 desand 2i are each-provided at a medial point-with 5 ;v ignates generally a bottom structure'for a wire the V-shaped extensions 21 and28 and'a conto I I I the supporting member comprising the plate 34 necting or dividing bar 29 is secured to the V- shaped members 28 at the convergent or inner ends thereof, thus dividing the basket into two s 28 thus providing four plates at each corner of 'each chamber 30 and 3|.

welded or otherwise fixedly secured to the basket I0 and each plate 34 is provided withreverted opposite end portions 35 which provide channels or guides on the oppositevertical edges of the The plates 34 areplate 34 within which the U-shaped supporting portion 36 of a glass clamping or holding member 31 is adapted to engage. The U-shaped. supx porting member 36 is provided with a substantially V-shaped lower,end portion 38 and the holder 36 is provided with bulges or arcuate offset portions 39 at the upper ends of the V-shaped member 38 which are adapted to project laterally through elongated slots 4|] provided in and the reverted or channelled member 35. The

holder 31 comprises a pair of arcuate arms 4| which are integral with the U-shaped supporting member 36 and the arms 4| are provided with reverted free end portions 42 forming eyes. The arms 4| are of resilient construction and are normally biased toward each other so that when a tumbler T is inserted therebetween the arms 4| will'be yieldingly forced apart and'will yieldingly hold the tumbler T in inverted position on apair of bottom bars |2 with the open end of the tumbler l0 engaging over a-pair of bar extensions |5.

In Figure 1 there is disclosed only one tumbler clamping member 31 but it will be understood that each holder comprising the plate 34 and 31 are adapted to be welded together and then coated with a suitable coating such as tin or the hke so as to resist corrosion from th'cleaning Inv the use and operation of this basket the arms 4| of the clamping members 31 are adapted to be spreadapart so as to permit the insertion of the tumbler T- therebetween, with the tumbler in an inverted position and with the open end thereof enclosing a pair of bottom bar extensions l5. These extensions l5 are adapted .to loosely engage within the open end of the tumbler "and so that these clamping arms 4|, will yieldingly clamp about the reduced portion of the tumbler or glass. The basket herein disclosed is adapted to be used with a cleaning or drying machine, which has a movable carriage or basket support.- ing member so that the bottoms of the tumblers are adapted to be engaged by combined cleaning and clamping devices and the entire structure then immersed in the cleaning fluid where the interior cleaning devices are adapted to project upwardly between pairs of the bottom bars I 2 so as to clean the inside of the glasses. After the glasses have been thoroughly. brushed in the cleaning fluid, the basket having the glasses.

mounted therein is then moved to a rinsing station where the glasses are thoroughly rinsed and from this station the basket still containing the same glasses is shifted to a drying station. After the glasses have been dried the glasses may be removed from the basket and the clamping ,members 31 or if desired, the glasses may be left in the basket and a number of these baskets stacked one upon the other. Preferably, however, the glasses are removed from the basket when they have passed the drying station orzone associated with the cleaning machine.
